12v Solenoid Valve for Gas Supply

[Ian_Rob]

Anybody using a solenoid valve to turn their gas on and off?

I did on my previous boat. I think it's a requirement for a gas fitness cert in NZ but many European-built boats don't seem to have them. Something like this:

ITYWF that one draws nearly 1 amp all the while it is open which could be a bit too much for a boat but Ok for an RV or a caravan with an electrical hook up.

This one draws a high current briefly but then reduces to a much lower current

I think so called ‘latching’ solenoid valves are made, where the current opens the valve but a reverse polarity has to be applied to close it. That presumably would sidestep the current draw issue? Not sure whether they are available at 12 volt or if such a system could be signed-off by a Gas Safe Engineer ?

I think the connection diameter is a too small but something along these lines:

I have one that draws about an amp on the boat. Turning it on only when needed gets to be habit when living aboard. As the valve is in the lazarette it does isolate the gas supply when off. To my mind the higher current valve increases safety as there's more reason to turn it off ?

I bought one a couple of years ago and it's still sitting in my workshop...

So did I mainly due to the high current draw of the valve when in use

Have just bought said valve and associated alarms - all good. Had a solenoid and alarm on the previous boat and wouldn’t be without either. I have a Truma solenoid valve for sale In For Sale section.
